Title: Rear ventilated wall cladding fixture - has substructure elements set cross-ways with holes for air passage whilst excluding insects
IPC: E04F13/00
Filed: 1978-07-14
Abstract: The cladding is fixed at an interval prescribed by the height of the retaining substructure, to provide rear ventilation between it and the wall. The substructure (2) has components aligned transversely to the direction of air flow, with holes in them for passage of air. These may be angled profiles with suitably aligned apertures (15), of cross-section preventing insects from passing through, and with one shank connected to a cladding panel, and the other (18), with the apertures in it, to the wall (5). This permits passage of air through the bottom edge, without allowing insects into the intervening space.

Title: IC engine fuel injection system - has pressure valve assembly with diaphragm as moving valve coacting with fixed valve seat on fuel suction side
Inventor: KNAPP HEINRICH DIPL PHYS DR
IPC: F02M69/54
Filed: 1979-05-08
Abstract: The injection system increases fuel metering precision by reducing variations of the system's operational pressure. The metering valves (7) are actuated by an air sensor (3), and they can hold a constant pressure difference via control valves (24), this difference being adjustable in accordance with engine performance. The control valves are incorporated in a pressure control line (32), also containing an electromagnetic valve (37). The operational pressure of the injection system is controlled by a pressure valve (57), having a diaphragm (57) as the moving valve part. Parallel to this valve is connected a pressure control valve (64) with a conical valve cone (65). The latter permits fuel flow, after engine stopping, until the pressure in the injection system has been reduced below the injection valve's opening pressure. The pressure control valve function can be taken over by the electromagnetic valve, also designed for rapid pressure reduction after switch-off of engine.

Title: Electronic control of branch exchange from main stations - with redundant data channels connected to alternative control stations to cover possibility of main exchange failure
Inventor: POLLACK WOLFGANG
IPC: H04Q3/00
Filed: 1979-09-17
Abstract: The proposed redundant circuit design is applicable to telephone systems in which branch exchanges are supervised and controlled from main or central exchanges by electronic controllers and data links. The security of operation is improved if the main and redundant data transmission circuits (0,1) between branch (GVST) and main exchange (STVSTI) are duplicated (0',1') to a second main exchange (STVSTII). Failures in a main exchange are thereby guarded against and the branch can continue in service, controlled from an alternative exchange. The second pair of lines (0',1') can be permanently connected or switched on by a fault detector (ESE G). With the latter alternative a pair of interconnecting lines can be selected when required and dedicated lines dispensed with.

Patent DE-2950338-A1 (DE)
Title: Radio telephone installation in vehicle - has signal monitor which adjusts amplifier gain dependent upon signal type being received
Inventor: ALDINGER MICHAEL DIPL PHYS
IPC: H04Q7/32
Filed: 1979-12-14
Abstract: In the radio-telephone system, the calling tone, or dialling tone, are made audible over the loudspeaker or head set. In order to minimise loading, and prevent overloading, the gain of the amplifier in the receiver is made dependant upon the signal type being received. Maximum gain is selected when a calling signal is received and recognised. This ensures that the tone will be heard over the background noise. During speech transmission an average value of gain is selected, and during pauses, or when quiescent, the gain is set to minimum. Calling tone recognition is by means of specially transmitted start codes which are decoded and used to set the automatic multiplexer controlling the gain in conjunction with the amplifier output. The actual gain variation is controlled by solid state switching of feedback resistors.

Title: Polystyrene or similar blocks shaped at joint faces - by steam heat and pressure, to compact material adjacent to joint and render it stronger
Inventor: BRUESER WALTER
IPC: B29C44/56
Filed: 1980-05-22
Abstract: A method of deforming plastic blocks or the like for the purpose of making joints, typically sawtooth, dovetail or similar joints, consists of heating the block with steam under pressure and thus deforming its surface to the required shape. In a typical arrangement a block or panel of polystyrene is enclosed by a hollow steam-heated mould, and a tapered tool is pushed into its end as it softens. Both the mould and the tool have perforations for the passage of steam. The method is used for forming mating joints in blocks and has the advantage that the material is condensed, compacted and rendered stronger around the joints, exactly the opposite from the result achieved when edges are sawn or cut.

Title: Rotatable target assembly esp. using tritium for particle accelerator - has targets exposed successively to bombardment by movement of previous target
Inventor: ZELLER JUN ALBERT DIPL CHEM
IPC: G21K5/08
Filed: 1980-06-03
Abstract: A rotatable target assembly for particle accelerators, esp. a rotatable tritium target assembly, is intended for generating neutron beams, esp. in cancer therapy. Two or more targets of circular shape or circular cross-section and movable one relative to the others are used; each target can be moved so that in one position it itself is bombarded, while in a second position it permits bombardment of the next target in the series. In one preferred arrangement a number of disc-shaped targets are mounted rotatable about a common axis; each target possesses an aperture which, in the appropriate position, can permit the passage of the bombarding beams to the next target. In another embodiment, a number of concentric targets of decreasing size, each of truncated conical shape, operate on a similar principle. A very lage number of targets can be incorporated in one compact appts., thus providing a long target operating life without need to interrupt use of the appts. in order to change targets.

Title: Leakage prevention system between coaxial components - uses higher pressure barrier medium in groove adjacent to fluid chamber
Inventor: GEISSER EDUARD
IPC: F16J15/40
Filed: 1980-07-15
Abstract: The system prevents leakage through a gap between two coaxial components, moved in relation to each other by fluid pressure. Two annular grooves, spaced in the axial direction are formed in one component, having connecting passages for a barrier medium reaching a lubricant film between the components delivered to one of the grooves and discharged from the other. The pressure of the barrier medium is higher than that of the actuating fluid, and the barrier medium is delivered to the groove (4,4') adjacent to the chamber (5,5') accommodating the actuating fluid. Both fluids are preferably supplied by a common source (Q,Q'), while a throttle (2,2') is incorporated in the actuating fluid supply line.
